KDE Platform Version: 4.4.5 (KDE 4.4.5)

Operating System: Linux 2.6.32-5-686 i686
Distribution: Debian GNU/Linux testing (squeeze)

-- Information about the crash:
I was in Removable Devices, where I wanted to clean a long list of old devices that auto-mounted on login just because I had mounted them once. So, after hitting Forget Device a couple of times, System Settings crashed.

 -- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
